The AOC 27B1H is a popular monitor due to its affordable price for an IPS panel display with an ultra-slim design. If you are interested in this monitor, there are a few additional things you should keep in mind though.
The monitor is based on an IPS panel with 8-bit color depth (6-bit + 2-bit dithering) and ~95% sRGB color gamut.
Although that’s a bit lower sRGB color space coverage than the preferable 99%-100%, the difference isn’t crucial unless you plan on doing color-critical work.
The colors are vibrant and consistent, and they won’t shift in tone when you look at the screen from different angles thanks to the wide 178-degree viewing angles.
Other panel-related specifications include a 250-nit peak brightness and a static contrast ratio of 1,000:1 which is standard for a monitor at this price range.
The AOC 27B1H display has a screen resolution of 1920×1080 pixels which, when stretched out on its 27″ screen, results in a pixel density of 82 PPI – pixels per inch.
In comparison, a 24″ 1080p display has a pixel density of 92 PPI and a 22″ 1080p display has 102 PPI. So, the image will be a bit more pixelated on the AOC 27B1H.
For general multimedia entertainment and video games, the low pixel density is bearable, especially when you apply some anti-aliasing in games.
However, if you want a sharper image, go with the 24″ model of this monitor instead – the AOC 24B1H which actually has a VA panel instead of IPS and therefore a higher contrast ratio as well.
When it comes to the performance, the AOC 27B1H monitor doesn’t have any issues, but it’s missing certain important gaming features such as AMD FreeSync and Motion Blur Reduction that other similarly priced displays do offer.
Its input lag amounts to 12ms at 60Hz which is enough to eliminate any delay between your actions and the result on the screen.
The response time speed of the AOC 27B1H is specified as 7ms (GtG) and 9ms (GtG) in different spaces (product webpage vs product datasheet).
While the response time is slower than that of most IPS displays which have 5ms (GtG), there’s really no prominent ghosting in fast-paced games. But then again, the monitor does have a refresh rate of only 60Hz.
The AOC 27B1H has a flicker-free backlight and an integrated low-blue light filter. These two features will make sure you don’t get headaches or eye strain even after prolonged usage of the screen.
Moving on, the AOC 27B1H IPS monitor has four OSD (On-Screen Display) hotkeys next to the power button. The hotkeys are used for navigation through the OSD menu which can be a bit annoying as we’d prefer a 5-way joystick instead.
Besides the standard picture adjustment options such as contrast, brightness, sharpness, color temperature, gamma (three presets), audio volume (for headphones), and aspect ratio (16:9 and 4:3), there’s the Clear Vision feature which can improve the quality of low-resolution images.
There are also a few pre-calibrated picture presets (Standard, Text, Internet, Game, Movie, Sports) as well as four low-blue light modes (Off, Weak, Medium, Strong).
Unfortunately, the monitor does not support AMD FreeSync which would provide a variable refresh rate for compatible GPUs.
Design & Connectivity
The biggest selling point of the AOC 27B1H is its ultra-slim design with 1.5mm thin bezels at the top and at the sides of the monitor. Note that there’s also a 5mm black border around the screen. Further, you can only tilt the screen of the monitor by -4°/22° and it’s not VESA mount compatible.
Connectivity options are as scarce as the ergonomics as there’s only one HDMI 1.4 port, one VGA input, and a headphones jack.
Price & Similar Monitors
The AOC 27B1H price amounts to ~$135. At this price range, we highly recommend you go with the LG 24MP59G instead.
The LG 24MP59G offers AMD FreeSync up to 75Hz, 1ms Motion Blur Reduction, higher pixel density, wider color gamut, and a DisplayPort input (so you can use FreeSync with compatible NVIDIA cards as well). It does not have as thin bezels though.
While the AOC 27B1H does offer a decent image quality and an eye-catching design, there are simply better alternatives out there for the money.

The AOC 27B1H may look like a great display for the price, but there are many things it lacks under its ultra-slim design, which is why we recommend you get one of the alternatives we’ve mentioned in the review instead.
